Achieving a draw is not a bad result for PSG even though they are playing at home because after all they have collected a lot of points to stay at the top for quite a long time even if they lose one or two matches this is not a threat for PSG because the team is Being in second place doesn't appear consistent and PSG can focus a little on the UCL match next week because the UCL competition is very important for PSG, because they have locked in the League 1 trophy, now they want to get the UCL trophy even though it is very difficult for PSG to achieve.
PSG must be able to beat Real Madrid, Man City and also Munich if they want to win this trophy, even though we all know that beating teams in the same class as these 3 teams is not an easy thing to conquer, especially with PSG strength which is still not that good when compared to the 3 PSG teams only relying on Mbappe, while teams like Real Madrid, Man City and Munich have balanced squads.
Yes, it's not a big deal if it happens in Ligue 1, because the draw they received in Ligue 1 has no effect on them in the standings. Their points are far from the other teams and that makes them comfortable when they draw only once. But it will be a different story if it happens in the Champions League, because when they get this result in the first leg and play at home it will be a threat to them because in the second leg they will be more dificult to win.
In the first leg of the Champions League, they won 2-0 against Real Sociedad, it opened their chances of qualifying from the round of 16 to the quarter-finals. But they also still have to be careful because it could be that Real Sociedad can turn things around in the second leg later when they play at their own headquarters. Paris Saint Germain must prepare for it all, because if they make a mistake then they will feel something bad or be eliminated from the Champions League early. They must play as usual, because mentally they will certainly be better after their advantage in this first leg.
